CHAMFERIN G- TOOL.

rSpecification of Letters Patent No. 24,465, dated June 21, 1859'.

To all whom it may concern:

Be it known that I, VILLIAM JOHNSON, 2nd, of Hampstead, in the county of Rockingham and State of New Hampshire, have invented a new and useful Improvement in Tools for Ohamfering Soles for Boots or Shoes; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying' drawings, of which- Figure 1, is a top view; Fig. 2, a front elevation; Fig. 3, a rear elevation; Fig. et, a front end view of one of my improved chamfering tools. l

Such tool as exhibited in the dra-wings is composed of a knife carrier A, a stationary edge bearer B, a sole rest O, a spring proper D, and a knife E, the said knife being provided with a handle a, the whole being arranged as shown in the figures.

From the knife carrier a lip extends upward at a right angle and against a Sec'- toral arc or curved projection c, projecting downward from the sole rest C. A screw l passes through the said lip Z) and screwsl into one of a series of screw holes e, e, e, formed through the are c. Between the edge bearer B and the knife carrier A there is an extension from the sole rest, the same being carried backward therefrom and furnished with an opening 01' passage g for the reception of the knife blade which extends through the said opening as shown in the drawings and is held firmly Within the same by adjusting screws 7a, it, c', arranged in the projection or part F, as shown in the drawings and so as to act against both upper and under-surfaces of the knife. IVhile the knife carrier is at liberty to turn on the screw d, the screws L, it, t', not only serve to adjust the edge of the knife with reference to the edge bearer B, but operate to hold the knife with great firmness in any position in which it may be placed. The angleof the sole rest and knife is thus securely maintained which is not the case in so advantageous a manner in the chamfering tools patented by me on October 12th, 1858, and April 12th, A. D. 1859.

rlherefore, what I claim my present invention or improvement is My improved mode of supporting the knife E, and adjusting it with reference to the Sole rest and theedge bearer, Viz, by means of a carrier A, and adjusting screws, 7L, 7L, z', applied and arranged with respect to the sole rest O, the edge bearer B, and the presser D, substantially as described.

In testimony whereof I have hereunto set my signature.
